File::Util::Interface::Classic - Legacy call interface to File::Util
Provides a classic interface for argument passing to and between the public and private methods of File::Util. It is as a subclass for File::Util developers that want to use it, and provides some base methods that are inherited by File::Util::Interface::Modern, but the _remove_opts method is overridden in that namespace, whose more progressive version of that method supports both ::Classic and ::Modern call syntaxes.
Users, don't use this module by itself. It is intended for internal use only.
